HYDRAULIC MOTOR.

Specification of Letters Patent.

Patented July 3, 1906.

Application filed August 7, 1905. Serial No. 273,104-

To all whom, it may concern.-

Be it known that 1, JOHN S. GRAY, a citizen of the United States,residing at Springdale, in the county of Stevens and State ofVVashington, have invented a new and useful Hydraulic Motor, of whichthe following is a specification.

invention relates to hydraulic motors, and has for its object to providea simple, inexpensive, and durable device of this character in which ahorizontal water-wheel is mounted for rotation on a suitablesupporting-frame with the depending buckets thereof traveling in aninclined flurne or waterway whereby both the weight and velocity of thewater will be utilized in driving the motor.

A further object of the invention is to generally improve this class ofdevices so as to add to their utility and durability as well asto'reduce the cost of manufacture.

With these and other objects in view the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings, and pointedout in the claims hereto appended, it being understood that variouschanges in form, proportions, and minor details of construction may beresorted to Without departing from the principle or sacrificing any ofthe advantages of this invention.

In the accompanying drawings, forming a part of this specification,Figure l is a top plan view of a hydraulic motor constructed inaccordance with my invention. Fig. 2 is a transverse sectional view ofthe same. Fig. 3 is a detail side elevation of one of the water-buckets,showing the manner of supporting the same.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

The improved motor consists of a suitable supporting frame or platform5, provided with a vertical shaft 6, the latter being rigidly supportedon the frame by horizontal cross-beams 7, the ends of which are fastenedin any suitable manner to uprights or standards 8, preferably driven inthe ground at suitable distances from the frame, as shown.

Arranged concentric with the shaft 6 is an inclined flume or waterway 9,to the outer wall 10 of which is secured a circular track 11, said trackbeing preferably formed of anthat portion thereof op- 9 elevated andsecured to one of the uprights or standards 8. The inner wall 12 of theflume is connected to the frame. 5 by suitable braces 4, there beingsimilar braces 13, extending between the frame and the standards oruprights 8, so as to securely brace the several parts and reventrotation when the motor is in operatlon. annular shoulder 14 is formedon the upper end of the shaft 6, and engagingsaid shoulder and mountedfor rotation on the shaft is a disk or wheel 15, to which are ged, asindicated at 17, a plurality of radially disposed bucket supporting arms18. The arms 18 are each preferably formed in two sections, having theirfree ends secured together in any suitable manner and provided with aterminal pin or stud 19, upon which is j ournaled a wheel or roller 20,which bears against the upwardly-extending flange 21 of the circulartrack 1 1, as shown.

Pivoted to the free ends of the radial braces, at 22, are horizontalbars or bolsters 23, provided with centrally-disposed upwardly-extendinglugs or projec tions 24, while hinged, as shown at 25, to the bolsters23 are the Water-buckets 26. The buckets 26, which may be of anysuitable shape or size, are shown in the present instance provided withmarginal flanges 27, said buckets being supported in a verticalposition, while traveling in the flume or waterway, by means ofsupporting rods or bars 28, one end of each of which is pivoted to anupwardly-extending ear or lug 28, secured to the disk 15, while theopposite end thereof is pivoted to the central projection 24 of theadjacent bolster.

The projections 24 and the bars 28 are pro vided with one or moreapertures 29,whereby said bars may be adjusted vertically to regulatethe lateral movement of the buckets, said bars being locked in adjustedposition by clam ing-nuts 30.

It wil thus be seen that the buckets 26 are hinged to the bolsters,while the latter are pivotally supported on the radial arms, so that byraising or lowering the inner ends of the rods 28 the buckets may beadjusted laterally with respect to the pivot-pins 22, so as to centerthe buckets within the flume or waterway, and thereby prevent frictionalengagement between said buckets and the walls of the flume.

Secured to the free end of each radial arm is a connecting rod or bar31, the opposite posite the flume IIO I disk and bucket on the adbetweenthe the buckets end of which engages the jacent arm, so as to formbraces several buckets. By having hinged to the bolsters 23, as armscarrying said buckets travelup the elevated portion of the track andreach a position adjacent-the valve 38 said tilt on the hinges 25 topermit clear the inner wall of the flume, the buckets automaticallyreturning to vertical position assoon as they pass said Wall, as will bereadily understood. The rods-are preferably provided with wing-nuts 32,which engage the terminal threads of the rods, so that said rods may beadjusted to vary the throw of the buckets. Journaled on suitable pinsdeending from the bottom of the disk or wheel 15 are a series of--antifriction wheels or rollers 33, which bear against an annular trackor flange 33 and serve to balance the prevent undue friction.

to the wheel or disk 15 is a collar or drum 34 to which is fastened apair of sprocket-wheels 35, the latter being connected, through themediumof :a s rocket-chain 36, with a vertical shaft 37 ,so t at thepower generated by the motor may be utilized for driving suitablemachinery or for other puroses.

The bottom of the flume or waterway is rovidedwith a pivoted gate orvalve .38 for controlling the quantity-of water admitted to the flume,so that by swinging the gate downwardly to open position the water willvfiow through the opening in the bottom :of the fiume without affectingthe buckets.

The sprocket-wheels may be located above or below the bucket-carryingSecure v wheel or disk and, if desired, the device supported on asuitable raft in a stream and actuated by the current.

From the foregoing description it is thou ht the construction andoperation of the evice will be readily understood by those skilled inthe art, and further description thereof is deemed unnecessary.
